SHINGLE PLANING AND SIZING MACHINE.

SPECIFICATION forming part of Letters Patent No. 465,005, dated December15, 1891.

Application filed July 28, 1890. Serial No. 360,208. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN H. TROMAN- HAUSER, of Minneapolis, in thecounty of Hennepin and State of Minnesota, have invented certainImprovements in Shingle Planing and Sizing Machines, of which thefollowing is a sions both in width and thickness are carried by asuitable endless revolving conveyor-platform adapted to revolve uponsuitable car rier-wheels after the mannerof a link belt andsprocket-wheels. This moving platform is firmly and adjustabiy supportedbeneath the planer and. is divided into a number of sec tions, eachindependent of the other, the width of each being determined by thevarying widths of the shingles desired to be manufac-' tured, severalwidths of shingles being made by the same machine. After passing underthe planer the shingle-blankis cut up into several sections by suitablecircular saws revolving between the several sections of the platform,the complete shingles being then taken from the machine and thrown intothe various bins by the sorter or allowed to drop from theplatform-links as they are carried beneath the carrier-wheel.

My invention consists, further, in' various details of construction andcombination hereinafter described, and particularly pointed out in theclaims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a sectional side elevation of a shingle planing and sizingmachine embodying my invention,the section being taken upon the line atm of Fig. 2. Fig. 2 is a plan view thereof. Fig. 3 is a sectional endelevation of my machine, as seen from the line l/ 'y of Fig. 1. Figs. 4and 5 are detail views of the platform-links which make up the endlessrevolving platform. Fig. 6 is a detail view showing the construction ofthe variable feed device shown in connection with the moving platform.Fig. 7 is a detail view showing the manner of disengaging the two disksof the variable feed. Fig. 8 is a detail.

Similar figures of reference are used upon like parts throughout thedrawings.

As will be seen by the drawings, the revolving platform is made up ofthe endless chain of short platforms or links 2, adapted to rotate oversuitable carrier sprocket wheels or drums and 4:, provided in suitableadj ustable bearings at the ends of the upright sides 5 and 6 of themachine. These links2 are of the pattern shown in Figs. 4 and 5,consisting of the plate 7, having the inclined upper face 8, as shown,and provided with the shoulder or foot 9, extending upwardly and bearingthe notched steel retaining-strip 10,-

the screws of which are countersunk into the plates, so as to be flushwith the surfaces thereof. Suitable lugs 12 and 13 are provided upon theopposite ends of the links 2, the adjoining lugs of the several linksbeing connected by suitable rivets or bolts, the heads of which areflush with both surfaces of the lugs. The platform composed of theseveral links 2 is divided longitudinally, as shown, into theendless-link-chain sections 15, 16, and 17, each longitudinal sectionbeing supported and guided by a bed-plate 18, 19, or 20, respectively.These bedplates are preferably provided wi h the downwardly-turned ends21, serving to guide the links onto the plates, and are in turn rigidlysupported between the sides 5 and 6 by suitable cross-bars or tie-beams23 and 24 and a suitable stationary support 25, placed midway betweenthe ends of said plates. The planer 26 is adapted to rotate rapidly inthe direction of the arrow, and is belted directly to the pulley on theend of the saw-arbor 27, which carries the several saws 28, projectingup between the said sections of the platform, as shown, and adapted tocut the wide shingle-blanks into different determined widths. The springpresser-feet 29 and 30 are adapted to prevent lifting the shingles fromthe platform by the revolving planer-knives. Suitable spring-rollers 31are provided upon either side of. or between the circular saws 28, andare adapted to prevent the shingles-from flying out of the saws as theyare passing between the same. It is desirable to plane only the thickbutt-ends of the shingle-blank. Hence the arrangement is such that theknives of the planer engage the shingle upon the platform only after thethin half of the shingle has passed beneath the same, the remainingportion bein'gthen planed down to the desired thickness. The

pitch or tilt of the platform-links as they pass form-links. Thetie-beams 23 and 24 are cut off 43 below the same and. which is adaptedto,

so as to just fitin between the sides of the machine, and are providedwith threaded openings into which the bolts 34 are adapted to bescrewed. These bolts pass through upright slots 35 in the ears 32 and 33and may therefore be adjusted in a higher or lower position, as desired.The bolts then being tightened up clamp the tie-beams 23 and 24 againstthe stationary connection to support the platformbed firmly in position.The platform bed or plates are free to move over the upper edge .of thecentral tie-beam 25 and tilt thereon as a fulcrum. The bearings of thewheels 3 and 4 are preferably made vertically adjustable, for when thetilt of the platform plates or bed is altered it becomes necessary, orat least desirable, to raise or lower the notched wheels 3 and 4, inorder that the strain upon the linkplatform may be as even as possibleand in order to avoid any tendency toward raising the links from thebed-plates.

As shown, the mainpulley 40, over which the main driving-belt passes, isprovided on the end of the planer-shaft. Upon the other end of thisplaner-shaft are provided the small pulley 41, over which the twistedbelt which runs the saw-arbor 27 passes, and the small pulley 42, overwhich a belt passes to connect the same with the large pulley-wheeloperate the large wheel 44 of the variablespeed device. Thisvariable-speed device may be constructed as shown in Figs. 2, 6, and 7,and consists in the small friction-pulley 45, adapted to press firmlyagainst the outer surface of the wheel or disk 44 to be revolved therebyand adapted to be moved back and forth between the center andcircumference of said disk 44 by a suitable lever 46, whereby the speedof the pulley 45 is controlled at will, the speed thereof being lessenedas it is moved in toward the center and increased as the friction-wheel45 nears the edge of the large drive-wheel 44. The 1ever 46 is adaptedto be locked'in position by l a suitable device 47, which is supportedby the branch arms 48, secured upon the beam 49, which is in turnpivoted upon the strap 50, secured upon the'adjustable bearing of thesprocket-wheel 3, serving to drive the moving platform. The pulley 45 ismovably keyed upon the shaft 51, which operates through a bearing on thebeam 49 and carries the smaller wheel 52 of the miter-gear adapted toturn the notched wheel 3. In order that the feed of the machine may bequickly stopped, I preferably provide means consisting in the adjustablelever 53, secured to the beam 49, which in turn supports the bearing forthe shaft 5l,wherebythe engagement between the small pulley 45 and thelarge disk 44 may be broken by moving out the small pulley 45 into theposition shown in Fig. 7.

I will now describe the operation of my machine, first stating that whenthe shingles are first sawed out of the short lengths of timber they areleft in the shape of'broad flat rough blanks having a tapering edge. Itis now desired to cut this shingle-blank into suitable widths and toplane down that por tion of the shingle which is exposed to the weather,so that at the butt=end of the shingle the edges will present theappearance of lying nearly parallel or perhaps slanting in a directionopposite to the original taper of the shingle. I will assume that themachine is in operation. The wide"- blanks are now placed upon the linksin front of the planer 26 in the position of the blanks 55 and 56, thebutt-ends being placed against the notched retaining-strip 10, as shown.As the platform is moved ahead the shingles or blanks are carriedthrough under the presser-feet 29 and the planer-knives. 'Theplaner-knives do not strike the thin edge of the shingle,'which firstpasses under the planer, and danger of the shingles being broken up bythe same being thus avoided; but as the last six or eight inches of thebutt-end'of the'shingle are passing through the planer strikes the sameand passed from under thefirst roller3l. The

several complete shingles are now carried over the end of the machine,and,"a's the links are carried around the wheel 3, fall off up'o'n ofthe machine. The blank in that case is merely placed upon the narrowsection, the edge being placed so as to just be cut by the outside sidesaw, while the other waste edge would be trimmeddown by the next saw. Amachine of the size shown and described could easily be fed with greatrapidity by a single man, who would place the blanks upon the platformin such a way as to make the least waste possible. For instance, if ablank were just wide enough to form two shingles of the width of the twowidest sections of the platform, the operator would place the blank uponthose sections rather than place it upon the two smaller sections.

As shown in Fig. 9, I prefer in practice to arrange a greater number oflinked platformsections than I have shown in the preceding figures, andI arrange the sections in groups of two or more having the same width.This arrangement is clearly illustrated in Fig. 9, where the sections ab and 0 cl and efarerespectively of equal Widths, each being sup portedby a suitable longitudinal bar, as hereinbefore described. The circularsaws are arranged to operate between the several sections. The advantageof this construction is that whereas a blank is often too narrow to maketwo shingles of thee and b widths it is wide enough to make two shinglesof the c and (Z width. Again, a blank not quite wide enough to make twoshingles of the a, andb width may be used on the sections 1) cf, therebymaking three good though narrow-dimensioned shingles.

It is obvious that gig-saws or band-saws might be employed in place ofthe circular saws; but I preferably employ the latter as most convenientand inexpensive. It is fun ther obvious that in the practicalconstruction of my machine various detail modifications would readilysuggest themselves to one skilled in the art, and I therefore do notconfine myself to the specific construction shown and described.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1.
